It will pay him 5 million if he's on the roster past a certain date. It's almost certain Arizona is going to cut him before they have to pay him that. They are holding onto him as an insurance policy against injury and out of delusional hope that someone will give something up for an aging RB that will be a FA in a bit anyway.

Edge is pissed because the money out there is running out and he's going to get "screwed" with a "low" salary.
